Dane knew from a young age he would be a speaker of God's word. He saw in the world the great evil and he vowed one day to confront and defeat it. He traveled the world and joined the Jesuit order in 1980. It is believed that in 1982 on the streets of Georgetown, Washington, DC , Dane encountered a Caitiffvampire. He was able to escape from her then hunted her for weeks after. When he finally found her and caught her he learned of her fear of fire and used it against her. The Caitiff was destroyed but he was scarred by the flames himself. Since then he has not been afraid of flames.

He has been hunting vampires ever since. A quite, careful, and driven hunter. He left the Jesuit order when the Church was unwilling to believe him about the Vampire's existence. He set out to perform the Lord's work against such evil while the whole time attempting to prove the existence of the Vampire to the Church.

Sullivan Dane knows and understands much about the Kindred and their folklore. And may have contact the Inquisition at some time but as of yet not officially joined them.
